| In recent years,with the continuous progress of railway modernization,China’s highspeed railway operating mileage has exceeded 40,000 kilometers,and the railway signal system as the core of traffic control,its intelligent,information,automation technology development is naturally self-evident importance.As an important part of railway signal system,the development of decentralized and self-regulated centralized dispatching system directly determines the efficiency and safety of railway operation and transportation.Therefore,it is of great significance to strengthen the development research and function optimization of CTC system.Based on the project of "Jinan CTC3.0 Station Subsystem Function Research and Development and Upgrade",this thesis realizes the design of station planning and splitting function,operation process management and control function and access selection and discharge card control function module of Jinan station subsystem,and verifies and tests the design results through the simulation platform.The optimization and upgrade systematically realized the development and deployment of the core functions of the CTC3.0 station subsystem,especially provided a solution to the problem of how to automatically compile and split the center plan of complex hub stations and open the CTC automatic routing.The main research work of this thesis includes:(1)Summarize the domestic and foreign research background and application status of decentralized self-regulated dispatching centralized system,briefly introduce the station situation and business requirements of Jinan Railway Station,analyze the subsystem architecture and functional requirements of CTC station,establish the system architecture model,and clarify the research idea of designing by dividing functional modules.Determine the overall design requirements of each function module and the goal of function realization.The main core function modules include interface display function,mode conversion function,train operation function,shunting operation function and communication function.(2)in order to achieve the planning of jinan hub station split functionality,process management and control functions,and route chosen card control function,in this thesis,the complex of the hub station plan resolution algorithm is studied,through the plan break rules,completed the train operation adjustment plan of center issued information receiving and parsing,In this way,automatic batch planning and automatic CTC routing functions are realized.Through the design of a variety of trigger ways to achieve access to handle and open,support the station equipment in different modes of operation under the effective control;Add the card control function of wrong route handling,the card control function of equipment status and the card control function of operation process,realize the safety check in advance,reduce the manual error rate,guarantee and improve the safety and efficiency of driving operation.(3)With the help of the simulation test platform,the overall joint adjustment with the CTC dispatching center,each field engaged line board,autonomous machine,vehicle terminal,interlock,RBC and locomotive is realized by using the accounting diagram of Jinan Station.The verification test of the above functions is carried out through examples to verify the feasibility and correctness of its core functions,so as to achieve the design goal.Finally,the main work of this design is summarized,and the problems existing in the research process and the prospect of future research are put forward. |
